LISTEFL,

SPECIFICATION forming part of Letters Patent No. 732,140, dated June 30, 1 903. I

Application filed January 27, 1902. Serial No. 91,315. (No model) To a. whom it may concern.-

Be it known that I, SAMUEL H. TINSMAN, a citizen of the United States,residing at Davenport, Scott county, Iowa, have invented certain new and useful Improvements in Listers, of which the following is a specification.

My invention relates to machines for planting corn or other grain, and more particularlyto machines of this character involving a plow or similar device for making a furrow and also suitable mechanism for dropping or depositing the corn or other grain in the furrow thus made. Planting-machines of this description are ordinarily known as listers and usually comprise, in addition to the foregoing elements, a suitable frame or body structure, a'suitable number of vehicle or supportingwheels, and also suitable means for causing a relative shift between such wheels and the frame or body structure, so as to permit the plow to be raised and lowered or adjusted with respect to the charactor of the work.

Generally stated, the object of my invention is to provide a simple, compact, and thoroughly-efficient construction of lister.

A special object of my invention is to reduce the weight and number of parts and at i the same time to insure the requisite strength and rigidity.

Furthermore, it is an-object of my invention to provide an improved arrangement whereby the raising of the plow will operate to automatically disconnect the dropping mechanism from the driving means, so that the plow can be raised and the machine drawn forward without operating the dropping mechanism.

Another object of my invention is to provide a machine of this character wherein the supporting-wheelsare all connected with and controlled in their movements relatively to the plow and body frame by a single bandlever.

A further object of my invention is to provide a construction and arrangement whereby the plow-beam may be advantageously employed to serve as the frame or body structure of the machine, thereby obviating the necessity of employing cumbersome and ob- -shown in Figs. 1 and 2.

jectionable supplemental frames or body portions.

It is also an object of my invention to provide an improved arrangement whereby a crank-axle and a bell-crank may be advantageously combined and arranged to cooperate in moving or shiftingthe supportingwheels relatively to the plow and plow-beam for the purpose of either raisingor lowering the plow.

In addition to these it is a special object of my invention to provide an improved arrangement of power-transmitting connection between a wheel on a crank-axle and the dropping mechanism.

My invention also involves an improved arrangement whereby a spring may be connected with all of the supporting-wheels, and thereby advantageously employed for assisting in lifting the plow from the ground.

The nature and operation of my invention, together with other advantages, will, however, hereinafter more fully appear; and to the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 shows one side of a lister or planting-machine involving the principles of my invention. In this view the plow is shown in a lowered or working position. Fig. 2 is a viewsimilar to Fig. 1, but showing the opposite side of the machine. Fig. 3 is a plan of the machine Fig. 4 is a view of the same side of the machine as shown'in Fig. 1; but in this View the plow is shown raised from the ground. Fig. 5 is a sectional detail view showing the discharge-spout for the seed or grain and also showing the swivel or pivotal connection between therear trailing or 'caster wheel and the plow-beam. Fig. 6 is a detail sectional view of the bearing-bracket,

which is inountedupon the crank-shaft and which supports a portion of the power-transmitting connection between one of the sup-- porting-wheels and the dropping mechanism. Fig. '7 is a bottom view of the bracket-bearing and adjacent parts shown in Fig. 6. Fig. 8 is a detail sectional view illustrating a portion of the power-transmitting connection between the rotary dropping mechanism and the driving-wheel and showing the cam device for automatically disconnecting the dropping mechanism from the driving-wheel when the plow is raised from the ground. Fig. 9 is a bottom view of the devices and parts shown in Fig. 8. Fig. 10 is an enlarged detail view showing a portion of the driving-wheel and a portion of the sleeve connection between this driving-wheel and the sprocket-wheel which forms a part of the power-transmitting connection between said driving-wheel and the dropping mechanism.

As thus illustrated my improved lister or planting-machine comprises a plow A, which, it will be observed, is preferably provided with a double moldboard, so as to throw the dirt to each side. The machine also comprises, preferably, a plow-beam B of any suitable form or construction and having its rear end secured in any suitable manner to said plow. As a matter of special improvement this plowbeam is preferablyadapted and arranged to serve as the sole or only frame or body structure with which the machine is provided. This obviates the necessity of providing any supplemental framework or body structure, and in this way the weight of the machine is reduced to a minimum, and, furthermore, strength and rigidity are secured with a comparatively small number of parts. To such end the forward supporting-wheels O (J are preferably mounted on the spindles or end portions of the crank-axle D, which extends transversely below the plow-beam at a point preferably substantially above the plowpoint. The middle portion of this crank-axle is preferably mounted to turn in a bearing D, which is preferablyin the form of a casting properly fitted and bolted to the plowbeam. Preferably there are only three wheels in number, the third wheel being in the nat-u re of a rear trailing or caster wheel E. This caster-Wheel is preferably somewhat smaller than the forward supporting-wheels and is provided with a stem 6, which is arranged to turn in-a box or bearing e. In this way said caster-wheel is free to swing or shift from side to side relatively to the balance of the machineand to trail behind the machine in the manner of an ordinary caster-Wheel. In order that this rear trailing or caster wheel may, like the forward supporting-wheels, be shifted .or adjusted relatively to the plow and beam, so as to cooperate with the forward supporting-wheels in raising the plow from the ground, the said box or bearing a is preferably connected with the rear downwardlybent portion of the plow-beam by means of links or swinging arms c and e, arranged preferably, as shown, in upper and lower pairs, the members of each pair being arranged at opposite sides of the plow-beam and box or hearing e. These links or swinging arms permit a relative vertical movement between the plow and the wheel E and serve as a swinging connection whereby the plow and beam may be raised and lowered at will. Preferably the construction and arrangement are such that all three supporting-wheels are connected with and controlled by a single hand-lever F. This lever is preferably pivoted to the plow-beam at f, is provided with a dog or locking device f, adapted to engage a rack f and is also preferably connected by a link f with a crank-arm d, rigidly secured to the crank-axle D. Onevof the links or swinging arms 9 is preferably provided at its lower end with a downwardly-extendinglever-arm e, which gives said link or swinging arm the character of a bell-crank. The lower end-of this downwardly-extending arm 6 is preferably connected, by means of a link or connecting-rod 6 with the crank-arm cl on the said crank-axle. This link or connecting-rod preferably has its rear end provided with a reduced portion 6, which is threaded to engage a threaded socket in the end of the turnbuckle or adjusting member 6 With this provision the said turnbuckle or adjusting member 2 can be detached from the bellcrank lever and can then be rotated, so as to, in effect, either lengthen or shorten the link or connecting-rod e With the said handlever thus connected with the forward crankshaft and with the latter connected with the rear supporting-wheel the raising and lowering of the plow or, in other words, the relative adjustment between the plow and the supporting-wheels is accomplished through the medium of a single hand-lever. When the lever is thrown forward, as shown in Fig. l, the plow is lowered to a working position and the machine is in an operative condition. When the lever is drawn back, however, as shown in Fig. 4:, the plow is then raised from the ground, the effect of pulling back the lever being to throw the supporting-wheels downward relatively to the plow-that is to say, to practically throw the wheels downward relatively to the plow, it being observed that, strictly speaking, the effect of rotating the crank-shaft and of rocking the bell-crank about its fulcrum or pivotal point e is to either lift or depress the plow and beam, ac cording to the direction in which the handlever is moved. The wheels are all connected with and simultaneously controlled or adjusted by means of a single hand-lever; but the movement is only relative, the wheels, of course, remaining on the ground while the plow and beam rise or fall, according to whether the machine is to be rendered inoperative or operative. With this simple and novel arrangement and connection of the supportingwheels the raising or lifting of the plow can be facilitated by connecting the crank-shaft with the forward portion of the plowbeam by means of a spring G. The spring thus applied and arranged assists the operator in lifting the plow from the ground. At this juncture it will be observed that the said operator occupies a seat H, secured at the upper end of an upright h, which preferably rises from the box or bearing 6. In this way the weight of the driver or operator is supported more grain, orseed is deposited in this furrow may be of any suitable form or character. As a matter of further and special improvement, however, this dropping mechanism is preferably so connected with a movable member of the machine that the raising of the plow from the ground serves to automatically disconnect the rotary dropper, and thereby discontinue the discharge of the corn or seed. To such end the grain or seed can be carried in a suitable hopper I, which is preferably supported by the plow-beam at a point immediately in front of the drivers seat H. It will be readily understood that the mechanism at the bottom of this hopper for releasing the grain or seed or, in other words,

dropping the same into the furrow can be of any suitable known or approved form. Preferably a spout I leads downwardly from the bottom of this hopper to a point immediately in the rear of the plow A. As stated, the grain or seed iscarried by the said hopper and is released or dropped into the dischargespout by the dropping mechanism. For example, this dropping mechanismcan be of the well-known rotary type, and the lower or rotary membert' can be provided with a bevelgear adapted to engage a relatively smaller bevel-pinion t" on the intermediate or counter shaft 1' This shaft, it will be observed, is arranged immediately below the hopper and dropping mechanism and is preferably supported in bearings formed by the brackets 2' which support said hopper. Preferably this shaft is capable of longitudinal or end movement with respect to the aforesaid automatic disconnection of the dropping mechanism when the plow is raised from the ground. The end of said shaft '5 can be provided with a sprocket-wheel i and connected, by means of a sprocket-chain 2' with a second intermediateeor counter shaft 2'. This intermediate shaft 2' is preferably supported in the bracketbearing 2' secured, preferably, to the crank shaft D. Suitable sprockets and a sprocketchain i serve as power-transmitting connection between this shaft i and the drivingwheel 0. This driving-wheel O can be connected in any suitable way-as, for example, bya sleeve cwith the sprocket, which is connected by the chain 2' with a sprocket on the shaft i A spring 11 is preferably arranged to hold the bevelinionrl in en a ement with P a a the bevel-gear 2'. Thus when the plowis in the ground the driving-wheel O is connected to transmit power and motion to the rotary member i, which, as stated, may be a part of any suitable form or construction of dropping mechanism. With the plow on the ground, as shown in Figs. 1 and 2, a forward movement of the machine causes the plow to form a-furrow in the ground and also causes the driving-wheel C to operate the dropping mechanism, the seed being intermittently dropped or discharged through the discharge-tube I and deposited in the furrow behind the plow. A link J is preferably arranged to connect the link or connecting-rod. c with the shaft 71 this link J having a slotj, in which the end of the said shaft travels. This linkJis preferably provided at its upper'end with a cam 0r bevel portion j, adapted to engage a correspondingly-beveled collar or link j on the shaft 1?. With this arrangement the bevelgear 71, as stated, is in engagement with the bevel-pinion 1 when the plow is in the ground andthe machineinoperativeposition. When the plow and beam are raised, however, as shown in Fig. 4, the cam or bevel portion 7" of the link strikes the bevel ring or collarj' and this causes the shaft 71 to shift longitudinally or endwise in a direction to move the bevel-gear 1" out of engagement with the bevel-pinion i. This, it will be seen, serves to break or open the power-transmitting connection between the driving-wheel and the dropping mechanism and to thereby discontinue the transmission of power from said wheel to said dropping mechanism. Thus the raising and lowering of the plow and the connecting and disconnecting of the dropping mechanism are simultaneously accomplished through the medium of a single lever. In other words, the raising of the plow,serves to automatically disconnect and stop the operation of the dropping mechanism, and the lowering of the plow operates to automatically throw the dropping mechanism into connection with the driving means. If desired, the said hopper I can be hinged, as at 1"", to the forward side of the ring i which is supported on the aforedescribed brackets At the rear side of said hopper it may be provided at its lower edge with a locking-bolt or similar locking device and with this arrangement the hopper can be readily unlocked and thrown forward, so as to permit access to be had to the under side of the dropping mechanismor to any of the other parts or devices located immediately below such dropping mechanism.

If desired, the crank-axle can be provided with a plurality of removable collars or sleevesections 0, so as to permit the distance between the two wheels to be varied. These collars or sleeve-sections c are, it will be observed, adapted to interlock and when adjusted into place form a practically-continuous driving-sleeve between the wheel and the sprocket for driving the dropping mechanism. As statedyhowever, any one of these collars or sleeve-sections can be removed and the wheel then adjusted or moved farther toward the plow, so as to reduce the space be- &

. oharacterized by a high lift and which, al-

though of a minimum weight and number of parts, is nevertheless strong and rigid and capable of eiiicient service in planting grain or seed. Furthermore, it will be seen that I although of this character and description said lister has all the necessary and desired adjustments and is readily and easily controlled with respect to the character of the work. The arrangement permits the bodily raising and lowering of the plow resulting from the relative movement between all three supporting-wheels and the plow-beam to be accomplished by manipulating a single handlever. Thus the operation of the lister is simplified and also the weight of the machine and the number of parts are reduced substantially to a minimum. As a further advantage the same lever which is employed for controlling the supporting-wheels is connected with the power-transmitting connection-between the dropping mechanism and the driving means in such manner that the dropping or discharge of the grain or seed is automatically discontinued when said lever is manipulated for the purpose of raising the plow. It will also be seen that the dropping mechanism and the hopper are advantageously located in front of the operator. In addition to this it will be seen that the crankaxle serves as a foot-rest for the operator or driver. As another advantage the plow is practically between the two wheels, and with this arrangement the plow does not tend to shift laterally and there is no lateral movement of the rear portion of the machine. As a further advantage the plow-beam is held at two points, thereby preventing the tilting or up-and-down movement which characterizes the ordinary lister havingthe beam held at but one point. With the relative arrangement of the operating-lever and the axle-arm d the plow-point is always below the heel, regardless of whether the plow is working at the surface of the ground or-at a considerable depth. When the plow is lowered to the ground, it stands substantially level, and when lowered into the ground its point or too dips relative to the heel, and the position of the point or toe relative to the heel is maintained at-all points in the adjustment of the plow below the surface of the ground. For example, in Figs. 1 and 2 the plow is shown lowered into the ground to a certain extent and the lever F is at a point which permits no further relative movement beween the plow and the caster-wheel E. In other words, a forward movement of the lever F from the position shown in Figs. 1 and 2 will produce further relative movement between the plow and the forward supporting-wheel,

but not between the plow and the rear supk porting-wheel. When the lever is thrown forward from the position shown in Figs. 1 and 2, the connection between the crank-axle and bell-crank e is simply moved vertically and not rearwardly, and hence this extreme forward adjustment of the operating-lever does not, as stated, cause any further relative movement between the plow and the rear supporting-wheel. It will be seen, however, that this extreme forward adjustment of the operating-lever causes the crank-shaft to rotate in its bearing, and consequently produce the desired further relative movement between the front supporting-wheels and the plow and plow-beam. In this way all three wheels are controlled and caused to shift relative to the plow up to a certain point in the forward adjustment of the operating-lever, and beyond such point the adjustment of the rear wheel ceases and the relative movement is confined to the forward supporting-wheels. Thus the plow is arranged for adjustment to any depth, and, as stated, the plow-point is always below the heel regardless of whether the plow is workingat the surface of the ground or at some depth. With the provision of a turnbuckle e the plow can be given any desired tilt or inclination, and this tilt or inclination is maintained at all points below the surface of the ground. Furthermore, the arrangement obviates the necessity of providing any means for locking the caster-wheel and also the necessity of providing a pole or tongue. It will also be observed that by placing the plow substantially between the two forward supporting-wheels it is possible to make a much shorter turn and to swing the machine around upon one wheel'as a pivotal 7 point.
